Thread Restoring Files

Nu-Thred® files are the highest quality with cross-cut and depth proportional to the thread pitch, so file will not skip or jump out of fine pitches. Also Nu-Thred® files are milled rather than cold-formed on a stamping machine, so the teeth are sharp and do the work rather than the mechanic's muscles. These files have been made by us to this high standard since 1947 in Reading, Pennsylvania, and will renew damaged external threads of any diameter (right or left-hand).
